Abstract

One of the major problems related to civil engineering structures is that of ground movements with amplitude ranges from a few millimeters to a few meters. Soil treatment by vibroflotation is a recent technique for improving soil with poor geo-mechanical properties. In addition, this treatment minimizes the risk of liquefaction and settlement. This Article is interested to establish diagnostic and monitoring of vibroflottation works, basing on the results of SPT tests, laboratory tests and quality control as well as the details of bathymetric and the properties of seabed soils before and after treatment. On the other hand, the work consists in making a in-situ monitoring using topographic hardware carried out on the treated soil, in order to verify its influence on the stability of the vertical breakwaters. The tests results will be compared with in-situ measurements.
